Design service for underfloor heating layout

You aren't designed to discuss without throwing your toys out of the pram

Things have been discussed argued, proven repeatedly over many years here - it is getting boring hence the short shrift given.

which isn't a very stable trait and those of us who don't feel the need to brag

Bragging, no. Stating the bleeding obvious - yes.

I'm sure you've heard that a million times though and probably from far nearer home.

Not really.

It only overshoots due to occupation. The UFH is off. I could tell you about a system that is being fitted that mitigates that too, but I can not due to legal reasons.
That's simple, ask them to leave.

What if I were to tell you it is a weather compensated system that runs rads upstairs and UFH downstairs and an unvented cylinder.
That would be how I expected it to be.

Warm up times do not catch us out as the house has sub zoning that gives each room the chance to control its own needs - the system thinks that everywhere is UFH even if it is rads.

How about this system:

Picture taken while in progress, 236 square metres of UFH with a couple of rads.

All working perfectly.... Customer is a regular whom we install several complete system a year for - nearly all UFH - in fact the job I am starting next week for him is 50/50 UFH and rads. All to be run from those pump stations with no local temperature control at the manifolds, btu each room zoned accordingly.

Last year we signed off another for this customer 8Km of UFH in one house. All happy as Larry.


YOUR small circle of chums may not have good experience, but that does not mean everyone does. And to assume an installation is going to be poor - as in implied by your and Bernard (who repeatedly proven to be ignorant of system design considerations and should be banned from the plumbing forum) detracts from the, no doubt, millions of miles of tube that is installed around the globe.
Those images are lovely, though clearly not the Joe Average domestic install. Again, nobody said everyone has an issue with the average domestic system and maybe others here that have UFH would like to express their satisfaction/dissatisfaction as a point of interest. I'd still hazard a guess UFH installs vary wildly out there much like they can with a radiator system but then with the nature of UFH being underfloor causes a bit more arséache for those suffering with a bad install.

That I get sometimes but certainly not all. There are lots of decent questions asked and given no time just a sarcastic retort.

There's that lacking character trait again. To you possibly some things are obvious but to the posters they are'nt, hence they ask. Yes, search could be used a lot more but those posters aren't really the ones shot down. The clever, legible posters are more often treated with contempt.


Not really.
Father Christmas is watching!
 
Care to explain how you are still here then and have not been driven off ?

Well, it's very clear. I'm simply a very highly regarded member. OK I've been banned several times, but when the hits were at an all time low & the resulting advertising revenues plummeted -I was drafted back in. I'd be interested to know your role here?? Court Jester?

Bernard, you only have to look across the numerous Internet forums to see he's treated like the drunk, old, píss smelling tramp taking up space on the park bench. His ego would be destroyed if he wasn't allowed to post how long he's been throwing boilers at the wall time and time again like every time is the first time.
If you're referring to me fine. But I do feel for the less fortunate in our society that you clearly ridicule. You clearly think you are superior & are void of any compassion. Perhaps you should reflect on your own current circumstances??
 
That ladies and gentlemen is how you wind up a wind up without any real effort.

Who do you think you're addressing, a captive audience???!!!!!..........:LOL::LOL::LOL::LOL:
Very few I'd imagine!! I don't know what's bigger, your ego or your head??!!.......:D
 
Love it... Only had one leak that wasn't of my making - and then I can't be 100% - only worked with Copper and stainless up to 54mm though. I've heard lots about Low carbon too :D.

Nice work Dan. Though the finer points & details of the install should be confined to the inner sanctum. The Finch has a black feather for comfort....:whistle:
 
Can you believe Dicky - it looks like this now.... A travesty. :(

Well, I say it looks like this... the timber is painted and their is a Utility room across the left wall now.

Atleast I can still service everything easily:

Hopefully the Sparks will have tidied up the cables by then :D.

So your customer for that installation is probably not the person who will be living in the property but an individual or company that develops properties for sale or rent. Developers tend to specifiy systems that provide the best financial return for them and the people who will be living in the property often have little or no input to the choice of heating system.

The graph you provided does show the slow reduction in temperature when the set point was dropped. I assume "occupancy" is the reason the actual temperature is above set point some of the time. Would that be heat from appliances ( computors etc etc ) adding to the heat energy still coming from the thermal mass of the floor after the UFH was turned OFF as it should be when ever the actual temperature exceeds set point temperature.

UFH with the thermal mass floor does tend to provide stable temperature control with slow rate of change of temperature. If that is what the people living in the house want then UFH is probably best for them. but not all people want a house that is at a constant temperature 24 hours a day.
 
My underfloor isn't on constant 24hrs a day.
It goes off overnight and a couple of hours during the day (doesn't lose that much heat so boiler doesn't ramp up to heat it again).
Also does my upstairs and TV room rads

And how are rads going to heat that space evenly

Not to mention look unsightly.

My system is technically a poor case as it is a 15mm overlay into a solid concrete deck sat on earth. No insulation at all.

Yet again you make a daft assumption. The pictured system is his own house. He is a builder who renovates private houses worth between 4 and 10 million. He trusts my judgement and has never had a dissatisfied customer in the 14 years or so we have been designing and specifying the systems that we fit for him.

Although to be fair, he isn't stupid, and has a good idea of what is required anyway.

The job starting this week is a carbon copy of his system apart from the extra rads. Necessitating some extra consideration of the target flow temperatures.

Will be a busy few weeks all in all.
